or customs duty

Tax levied upon goods as they cross national boundaries, usually by the government of the importing country.

The words tariff, duty, and customs are generally used interchangeably. Usually assessed on imports, tariffs may apply to all foreign goods or only to goods produced outside the borders of a customs union. A tariff may be assessed directly, at the border, or indirectly, by requiring the prior purchase of a license or permit to import specified quantities of the good. Examples of tariffs include transit duties and import or export taxes, which may be levied on goods passing through a customs area en route to another destination. In addition to providing a source of revenue, tariffs can effectively protect local industry by driving up the price of an imported item that competes with domestic products. This practice allows domestic producers either to charge higher prices for their goods or to capitalize on their own lighter taxes by charging lower prices and attracting more customers. Tariffs are often used to protect "infant industries" or to safeguard older industries that are in decline. They are sometimes criticized for imposing hidden costs on domestic consumers and encouraging inefficiency in domestic industries. Tariffs are subject to negotiation and treaties among nations (see General Agreement on Tariffs and Trade; trade agreement; World Trade Organization).

Introduction

also called  customs duty 

       tax levied upon goods as they cross national boundaries, usually by the government of the importing country. The words tariff, duty, and customs can be used interchangeably.

Objectives of tariffs

      Tariffs may be levied either to raise revenue or to protect domestic industries, but a tariff designed primarily to raise revenue also may exercise a strong protective influence, while a tariff levied primarily for protection may yield revenue. Gottfried von Haberler (Haberler, Gottfried von) in The Theory of International Trade (1937) suggested that the best way to distinguish between revenue duties and protective duties (disregarding the motives of the legislators) is to compare their effects on domestic versus foreign producers. (See protectionism.)

      If domestically produced goods bear the same taxation as similar imported goods, or if the foreign goods subject to duty are not produced domestically, and if there are no domestically produced substitutes toward which demand is diverted because of the tariff, then the duty is not protective. A purely protective duty tends to shift production away from the export industries and into the protected domestic industries or other industries producing substitutes for which demand is increased. On the other hand, a purely revenue duty will not cause resources to be invested in industries producing the taxed goods or close substitutes for such goods, but it will divert resources toward the production of those goods and services upon which the additional government receipts are spent.

      From the standpoint of revenue alone, a country can levy an equivalent tax on domestic production (to avoid protecting it) or select a relatively small number of imported articles of general consumption and subject them to low duties so that there will be no tendency to shift resources into industries producing such taxed goods (or substitutes for them). If, on the other hand, a country wishes to protect its home industries, its list of protected commodities will be long and the tariff rates high. Political goals often motivate the imposition or removal of tariffs. Tariffs may be further classified into three groups—transit duties, export duties, and import duties.

Transit duties

      This type of duty is levied on commodities that originate in one country, cross another, and are consigned to a third. As the name implies, transit duties are levied by the country through which the goods pass. Such duties are no longer important instruments of commercial policy, but, during the mercantilist (mercantilism) period (16th–18th century) and even up to the middle of the 19th century in some countries, they played a role in directing trade and controlling certain of its routes. The development of the German Zollverein (a customs union) in the first half of the 19th century resulted in part from Prussia's exercise of its power to levy transit duties. The most direct and immediate effect of transit duties is a reduction in the amount of commodities traded internationally and an increase in the cost of those products to the importing country.

Export duties

      Export duties are no longer used to a great extent, except to tax certain mineral, petroleum, and agricultural products. Several resource-rich countries depend upon export duties for much of their revenue. Export duties were common in the past, however, and were significant elements of mercantilist trade policies. Their main function was to safeguard domestic supplies rather than to raise revenue. Export duties were first introduced in England (United Kingdom) by a statute in 1275 that imposed them on hides and wool. By the middle of the 17th century, the list of commodities subject to export duties had increased to include more than 200 articles. With the growth of free trade in the 19th century, export duties became less appealing; they were abolished in England (1842), in France (1857), and in Prussia (1865). At the beginning of the 20th century, only a few countries levied export duties. For example, Spain still levied them on coke, Bolivia and Malaysia on tin, Italy on objects of art, and Romania on forest products. The neo-mercantilist revival in the 1920s and '30s brought about a limited reappearance of export duties. In the United States export duties were prohibited by the Constitution, mainly because of pressure from the South, which wanted no restriction on its freedom to export agricultural products.

      Export duties are now generally levied by raw-material-producing countries rather than by advanced industrial countries. Differential exchange rates are sometimes used to extract revenues from export sectors. Commonly taxed exports include coffee, rubber, palm oil, and various mineral products. The state-controlled pricing policies of international cartels such as the Organization of the Petroleum Exporting Countries (OPEC) have some of the characteristics of export duties.

      Export duties act as an effective means of protection for domestic industries. For example, Norwegian and Swedish duties on exports of forest products were levied chiefly to encourage milling, woodworking, and paper manufacturing at home. Similarly, duties on the export from India of untanned hides after World War I were levied to stimulate the Indian tanning industry. In a number of cases, however, duties levied on exports from colonies were designed to protect the industries of the mother country and not those of the colony.

      If the country imposing the export duty supplies only a small share of the world's exports and if competitive conditions prevail, the burden of an export duty will likely be borne by the domestic producer, who will receive the world price minus the duty and other charges. But if the country produces a significant portion of the world output and if domestic supply is sensitive to lower net prices, then output will fall; world prices would then tend to rise, and, as a consequence, both domestic producers and foreign consumers would bear the export tax. How far a country can employ export duties to exploit its monopoly position in supplying certain raw materials depends upon the success other countries have in discovering substitutes or new sources of supply.

Import duties

      Import duties are the most important and most common types of custom duties. As noted above, they may be levied for either revenue or protection, or both, but tariffs are not a satisfactory means of raising revenue, because they tend to encourage economically inefficient domestic production of the dutied item. Even if imports constitute the bulk of the available revenue base, it is better to tax all consumption, rather than only the consumption of imports, in order to avoid uneconomical protection.

      Import duties are no longer an important source of revenues in developed countries. In the United States, for example, revenues from import duties in 1808 amounted to twice the total of government expenditures, while in 1837 they were less than one-third of such expenditures. Until near the end of the 19th century, the customs receipts of the U.S. government made up about half of all its receipts. This share had fallen to about 6 percent of all receipts before the outbreak of World War II, and it has since further decreased.

      A tariff may be specific, ad valorem, or compound—i.e., a combination of both. A specific duty is a levy of a given amount of money per unit of the import, such as $1 per yard or per pound. An ad valorem duty, on the other hand, is calculated as a percentage of the value of the import. Ad valorem rates furnish a constant degree of protection at all price levels (if prices change at the same rate at home and abroad), while the real burden of specific rates varies inversely with changes in the prices of the imports. A specific duty, however, penalizes more severely the lower grades of an imported commodity. This difficulty can be partly avoided by an elaborate and detailed classification of imports on the basis of the stage of finishing (e.g., raw materials or finished goods), but such a procedure makes for extremely long and complicated tariff schedules. Specific duties are easier to administer than ad valorem rates, for the latter often raise administrative problems, especially concerning the valuation of imported articles.

      A list of all import duties is usually known as a tariff schedule. A single tariff schedule applies to all imports regardless of the country of origin. This is to say that a single duty is listed in the column opposite the enumerated commodities. A double-columned or multicolumned tariff provides for different rates according to the country of origin, with lower rates being granted to commodities coming from countries with which tariff agreements have been negotiated. Most trade agreements are based on the most-favoured-nation (most-favoured-nation treatment) clause, which extends to all nations party to the agreement whatever concessions are granted to the most-favoured nation.

      Every country has a free list that includes articles admitted without duty, but few conclusions about the impact of tariffs on trade can be drawn by looking at the free list and the value of the goods imported into a country. It is nearly impossible, furthermore, to measure the height of a tariff wall and to compare the degree of protection between countries by calculating the ratio of tariff receipts to the total value of imports. Using this approach, one might erroneously conclude that tariff protection is very limited in a country that exempts more than half of all imports from duties. Such a conclusion, however, is not correct, because some items are subject to very high tariffs, and, as those tariff levels increase, the quantity of the dutied imports decreases.

      A better method of measuring the height of a tariff wall is to convert all duties into ad valorem figures (based on the value of the goods) and then to estimate the weighted-average rate. The weighting should reflect the relative impact of the different imports; a tariff on foodstuffs, for example, may be far more significant than a tariff on luxuries consumed by a small group of people.

      In addition, a better understanding of protectionism can be reached through the effective rate of protection. It recognizes that the protection afforded a particular domestic industry depends on the tariffs levied against materials used to make the product (inputs) as well as tariffs levied on the final product (output). Suppose, for example, that half of an industry's inputs are imported and subject to a duty of 100 percent. If the imports with which the industry competes are subject to a duty of less than 50 percent, there is no effective protection. Calculating effective protection in a real-world situation requires complex economic analysis. (See international trade: Measuring the effects of tariffs (international trade).)

Tariff reduction and the growth of international trade

      For goods and services alike, international trade grew dramatically in the second half of the 20th century. By the year 2000, total world trade was 22 times greater than it had been in 1950.

      This increase in multilateral international trade occurred at the same time that trade barriers, especially tariffs, were reduced or in some cases eliminated across the globe. A major impetus to the global growth of trade was the General Agreement on Tariffs and Trade (GATT), a series of trade agreements adopted in 1948. The system created under GATT encouraged a series of trade negotiations focused on tariff reductions. The early trade agreements were largely directed toward tangible goods such as agricultural products, processed foods, steel, and automobiles. A round of negotiations known as the Uruguay Round (1986–94) finally led to the creation of the World Trade Organization (WTO) in 1995.

      Advances in information technology since the 1990s have altered the focus of many trade agreements. In 1997 the WTO's Information Technology Agreement (ITA) and Basic Telecommunications Agreement (BTA) reduced the tariffs on computer and telecommunications products and some intangible goods considered to be drivers of the developing knowledge-based economy. The rapid growth of the Internet and electronic commerce ( e-commerce) represented some of the most challenging new issues in the international trade arena, in part because many countries were slow to adopt bilateral free-trade agreements that included provisions covering e-commerce.

      The ITA and the BTA represented a dramatic departure from earlier national economic policies, especially in cases where countries used prohibitively high tariffs and subsidies to protect their technology industries from foreign competitors. Free-trade advocates and the WTO have held that WTO-sponsored agreements offer the best means of providing lower prices for consumers across a wide array of products while creating fairer competitive conditions for international suppliers.

      The work of the WTO came under increasing scrutiny from its critics, especially after 1999, when trade talks were disrupted by globalization protesters during the WTO ministerial conference in Seattle, Washington. These critics voiced a number of concerns about the power and scope of the WTO, with the gravest criticisms clustering around issues such as environmental impact, health and safety, the rights of domestic workers, the democratic nature of the WTO, and the long-term wisdom of endorsing commercialism and free trade to the neglect of other values. (See globalization (globalization, cultural).)

      There is no question, however, that tariff reduction creates many economic benefits. Proponents of the WTO have emphasized its positive results by pointing to reductions in the cost of living, increases in income, and improvements in efficiency. Although these advocates recognize the controversial nature of the organization's rules and principles, which call for lower tariffs among member nations, they insist nonetheless that the WTO provides a democratic forum for resolving conflicts in an open, reasonably fair, and transparent manner.
